The Pilgrim is a late Jacobean era stage play, a comedy by John Fletcher that was originally published in the first Beaumont and Fletcher folio of 1647.

The play was acted by the King's Men; they performed it at Court in 1621 Christmas season. Since Fletcher's source for his plot, El Peregrino en su Patria (1604), a prose romance by Lope de Vega, was first translated into English in 1621 (from the French translation, not the Spanish original), the play was likely composed and premiered on the stage in that year. The cast list added to the play in the second Beaumont and Fletcher folio of 1679 includes Joseph Taylor, John Lowin, Nicholas Tooley, John Underwood, Robert Benfield, George Birch, John Thompson, and James Horn.

The Pilgrim was both revived and adapted during the Restoration era, as were many of Fletcher's plays. Sir John Vanbrugh made a prose adaptation of Fletcher's verse original that premiered at Theatre Royal, Drury Lane in 1700, with a Prologue, Epilogue, and a "secular masque" written by John Dryden shortly before his death. The actress Anne Oldfield began her stage career in this production, in the role of Alinda. Vanbrugh's adaptation was also published in 1700, with subsequent editions in 1718 and 1753 (in London), and 1788 (in Dublin).

The play has attracted attention from critics for its portrayal of madmen and their keepers.

(The below scene divisions, taken from the edition of Alexander Dyce, differ slightly from those in the 1647 Beaumont and Fletcher First Folio.)

I.i: The old, wealthy Alphonso complains to his two friends Curio and Seberto that his daughter Alinda will not accept his match for her, Roderigo, and swears to force her to do so, although he is known to be an outlaw. His friends urge patience, and try to dissuade him from the idea that she favors the young Pedro, whom Alphonso hates. Alinda enters and is upbraided by her father while the two friends pity her. After some talk with her saucy maid Juletta, Alinda prepares for her usual charity of giving money to the poor. I.ii: An unnamed pilgrim enters with Pedro, who is disguised in pilgrim's garb. Initially silent, Pedro speaks to Alinda once the others leave, telling her "I seek myself and am but my self's shadow." After he leaves, Alinda bids Juletta bring a ring from her chamber, and she finds those precise words engraved on it.

II.i: Alphonso is enraged because Alinda is missing, alternately threatening Juletta and promising her gifts if she will tell him where his daughter is, while sending his other servants to search. They find that Alinda escaped through a gate for which she had a key, leading to a park on the estate, but cannot trace her steps further. Alphonso, Seberto, and Curio pursue her. II.ii: Meanwhile, Roderigo and four of his outlaws complain that they are letting too many travelers escape without plundering them. The outlaws have brought Roderigo a famished boy (the disguised Alinda), whom the latter intends to use as his servant. The outlaws Jacques and Lopes enter with Pedro as their prisoner. Roderigo has a grudge of long standing against Pedro's father and promises to kill Pedro in revenge, despite his holy pilgrim's garb. Pedro dares him to do it and professes himself unafraid. Roderigo calls for a halter and orders his outlaws to hang Pedro, but they refuse to have "religious blood" on their heads. Enraged, he goes to fetch the "boy" to hang Pedro. Brought in, the disguised Alinda convinces Roderigo that he can get a fuller revenge later by letting Pedro live now, fighting him at some future time. Persuaded, Roderigo lets Pedro go and exits with Alinda, to the amazement of his outlaw crew.

III.i: Roderigo interrogates his crew; they now know that the "boy", who has disappeared, was Alinda. A cantankerous Alphonso, who has lost his horse searching for his daughter, enters, and Roderigo promises to give him food and refreshment. III.ii: Juletta in a soliloquy reveals that she is the one who has been leading Alphonso on a fool's chase and caused the loss of his horse. III.iii: Seberto and Curio, wandering the woods, encounter the still-disguised Alinda, who claims to have been beaten by Roderigo's crew and escaped; they give the "boy" money. Then Alinda runs into Juletta, who doesn't recognize her until Alinda runs off at Roderigo's approach with some of his gang. III.iv-v: Jacques and other outlaws are maintaining the camp in their leader's absence, but scatter at the sound of Juletta's drum, thinking the king's army is advancing on them. Alphonso emerges from his rest disoriented and afraid, but Seberto and Curio appear and tell the re-entering outlaws that the noise was only a boy with a drum "hunting squirrels by moonlight". Alphonso tells his two friends that the boy they met with was Alinda, and they continue pursuit, trailed by Juletta.
